Official — built on Jev
First-party Jev resources published by TypeSafe AI: the company site, documentation, quick start, HTTP API reference, and community Discord. Everything listed here is maintained upstream, not by this directory.
Use these links to verify the numbers quoted across this site — such as list pricing of $0.042 per 1M input tokens with output tokens free, and an end-to-end latency range of roughly 70–500ms. Those figures come from TypeSafe materials, not from benchmarks run here.
